PHP drop down menu -

-

i doing select on database , time returns me 10 records , 1000, depending on criteria of search. want drop down have break after every 30 records. this

<select id="dd" >   <option value="0">1-30</option>   <option value="30">31-60</option>   <option value="60">61-90</option>   <option value="91">91-120</option> </select>

how do in php dynamically?

here's take on it:

echo '<select id="dd">'; $j = 0; for($i=0;$i<$numresults;$i++) {     if($i%30==0)         echo '<option value="'.$j.'">'.($j+1).'-'.($j+=30).'</option>';      } echo '</select>';

for $numresults == 130 output be:

<select id="dd">     <option value="0">1-30</option>     <option value="30">31-60</option>     <option value="60">61-90</option>     <option value="90">91-120</option>     <option value="120">121-150</option> </select>
